I wish it was that easy.
They all have their proponents and detractors.
I don’t promote any that are blacklisted at Casinomeister, I want happy players and I have a lot of return visitors. Occasionally I will promote one anyway because I feel I have enough pull there to be able to protect a player if needed.
Different ones work on different sites, depending on the type visitor and the feel and look of the site and whatnot.
If any of them worked for no one, they would stop paying an aff manager.
Conversely, it’s likely a good guess that places who have a decent staff working with affs are doing well for them.
Then you have new ones, quite a few lately, with well known managers that are very promising, and new ones often convert very well.
Try to stick with ones at CAP, there is a huge enough selection and I just can’t think of all the scammy ones that are out there. There are some really scammy ones. At least here at CAP you know they’ll pay you or all hell is lose.
